Subject: [PATCH 39/73] WIP: arm64: dts: meson: radxa-zero: add support for the
usb type-c controller
Radxa Zero uses an FUSB302 type-c controller, so lets enable it.
NB: Polarity swapping via GPIO is not implemented in the current driver
(see drivers/usb/typec/tcpm/fusb302.c) so it is not possible to handle
GPIOAO_6 for USB3 polarity control.
